bug: Operator OOMKilled

[xolott]

Describe the issue

The operator is constantly killed because of OOM issues. I upgraded the chart release increasing the memory limit to 100Mi. So far it's working

To Reproduce

Just install the operator and wait a few minutes

Expected behavior

It should work as usual

@wenchajun Have you ever had this problem?

I don't have this problem on my machine, but with the addition of the fluent-operator feature, I think it's possible to increase the container limit.

@xolott to reduce memory consumption, you can disable fluentd or fluentbit controller if you don't use it

helm install fluent-operator --create-namespace -n fluent charts/fluent-operator/ --set operator.disableComponentControllers=fluent-bit,fluent-bit.crdsEnable=false

I'm using both @benjaminhuo

So far, the operator is working fine with the limit change to 100Mi

[engin]

using Azure AKS 1.27 got the same OOM kill event for fluent operator 2.7.0

@engin You can follow the same step
